With the phone off .. Press 1 (on the keyboard) and power. If so, maybe try to odin back to EC05 stock

good luck

If on boot after pulling battery it is still black and download mode shows nothing, and you have tried Odin (it works but you see nothing still) I am afraid you need to head to the Sprint store.

try to odin to ec05 stock ... leave your phone again for a while and see when you get your screen back if you can get to download mode and odin that stock rom ... this will allow you to see if it is something up with a rom you're running.
if it does it then, you'll be at stock so when you go to the sprint store; it won't be an issue.

I agree Odin back to stock is your best option and if that dosn't work you probaly stuck with a black screen!

Yes, if you got it to come on once by leaving it you should be able to do it again and Odin before making any calls.

I had no choice but to take it to the sprint store
they fixed it !!!

Hey, I know this is an old post but I have an old Epic I'd like to see if I can trade into for credit towards a Galaxy S III but I'm having the exact same problem as described here:
Softkeys light up, screen hepatic feedback "buzz" can be felt, can swipe to unlock and answer a call based on blind-memory of what to swipe but other than that, the screen is completely black. Not black as in lit up but devoid of any other color except black, but gone dark.
If it weren't for the softkeys being lit, I would assume the screen were either broken or disconnected from the motherboard somehow. There are no cracks in the screen. Phone has seen better days for sure but the screen is intact and all functions were working perfectly before it simply...blipped off in front of my eyes.
I've tried doing as you did: charging it for 3+ hours and seeing if that worked at least temporarily. No go.
Assuming our two phones were experiencing exactly the same issue, can you tell me when you had it repaired, if the issue was a hardware or software issue? If hardware, did they have to replace the screen? or was it merely not connected properly somewhere?
If it was a software issue, how did they repair it? I'm assuming I can, in fact, get the phone into download mode, but without a visible screen, I can't boot off of a zip file or see if any of my actions are successful. Can't be sure I cleared the caches properly before I proceed, etc.
Phone was last running toadlife's CleanGB prior to the FC09 update and I'm pretty sure, prior to EL30 (I can't remember but I'm pretty sure it was).
Again, I know this is old but any feedback would be appreciated.

Hm, so you're saying download mode or recovery mode open up but with a black screen? But it still reads touches? My guess is it's hardware, a loose connection to the screen.

Yeeeeah, good luck towards funding your S3 purchase.

I'm having this issue have my phone was dropped yesterday, so I'm quite sure it's a hardware issue.
I have two questions: can somebody be so kind as to give me the button sequence for how to make a nandroid of my phone? I have CWM 5.0.2.7 without the 'one confirm' option. That would be awesome. Also, is anyone familiar with taking the phone apart and perhaps how to fix this issue?

Thanks tazfanatic. I tried the backup procedure and it didn't seem to work, and I think I actually have CWM 5.5. Is the procedure any different?

Indeed. I'm running CM9 beta 2, and I'm pretty sure it came with 5.5. However Taz, I believe if you boot into recovery from ROM Manger or the power menu, it still takes you into your previous recovery version (such as 5.0.2.7). Or vice versa. I don't remember. To my knowledge, this is has something to with the switch to MTD, and the devs just have reroute that command.
But regardless, I'm not getting a new backup on my SD card, so I'm pretty sure I'm on 5.5. Kenny, do you know if there's a different button sequence for 5.5?

5.5 is the same. I would remove the battery to make sure it is powered off. Put the battery back in, hold camera, volume down and power in that order (making sure power is last) for 5 seconds. wait 20 seconds to make sure it booted into CWM 5.5. Then volume down 4 times then camera twice. Depending on how many apps you got I would wait 30 minutes before pulling the sd card to check in clockworkmod\backup directory for a new file with current date code.

[Q] Galaxy Note 2 Black screen after cyanogenmod

Hi,
I installed the cyanogenmod 11 nightly like a week ago on my galaxy note 2 and all was running perfectly until this morning.
When I woke up this morning the phone screen was black. The phone is actually working, I can hear emails notifications, phone ringing etc.
The buttons light up when i press them. When I connect it to the PC I can browse the phone contents etc. All seems to function except the screen.
The battery is charged. I tried to remove the battery for a long time and try again but still nothing.
I can't get into recovery or download mode as the screen is blank (sometimes there is a like a weird area at the top where there are like different colored pixels present). I know people will say the screen might be damaged but last night before I went to bed it was all fine, the phone was placed on the table, and this morning when I picked it up screen is blank.
I want to flash back the stock firmware. However I can't get into download mode in order to use Odin. Is there any other way to get into download mode or hardware reset the phone?
Any suggestions are welcomed.
EDIT: The touch screen also seems to work when I touch it as I can for example call numbers for which I had speeddial scortcuts but it is still completely blank.

I think this is hardware issue. You must replace the screen

Yeah I think so too. I've sent it to Samsung.
It was rooted and had cyanogenmode so probably I have no warranty
However I managed to install stock ROM so hopefully they won't (can't) notice.

Lock Screen of Death (+ Some)

Ok guys, so I'm having an issue with my Note 10.1 2014 Edition. Whenever the screen times out, or you lock it, the screen will not come back on. The buttons will light up, but the screen is unresponsive. Hold the power button for a reboot and it reboots, screen works fine until the next lock. So obviously first thing, wiped everything, and reloaded Hypderdrive, only to get the same issue. So I go in again to recovery, and while I'm doing some research, TWRP times out and the screen goes black, and again, I'm unable to "wake" the device. Now I'm thinking hardware, but the power button is being recognized to lock it, so it should be recognized to unlock it as well and it is because the button lights come on. I've gone in, did a complete wipe including /system and /data and I'm currently trying to load a new rom to my microsd card to load, but the screen timed out again and I have to reboot the device back into recovery each time to get the screen to work. I'm pretty sure the root method I used, voided my warranty, so sending it in is probably not an option. When I reboot into download to check the status, It just says Downloading... Do not turn off target!! and I see no information in the top left of the screen. Anyone have any idea as to what could be causing the screen to do this? I'm kinda lost at this point! Thanks in advance.
P.S. So I was able to get into Download, and found my Current Binary is Custom, my System Status is Custom, and my Warranty Bit is 1, so I'd assume warranty is out of the option.
P.P.S I got a new rom loaded everything flashed fine, booted, let it set, when the screen timed out, again won't turn on. I can almost say 100% it's not a rom/Kernel issue. But beyond that I'm lost!

So I was messing with it some more after work today and found a few more pieces to the puzzle. After rebooting it in a bright room, I found the screen is on, but the backlight isn't. The screen is usable and responsive. Second thing is the brightness slider no longer works, it's just one brightness level and can't be adjusted. I've read online, that there maybe a loose ribbon cable, so I'm going to look into that alittle bit. I'm really hoping the backlight and LCD aren't shot! Again if anyone has any experience or ideas, please let me know!

SO I was using Triangle Away to try to clear the flash counter, as I was filling out a service request form from Samsung, and after the reboot the screen was brighter. I then tried the brightness slider..it worked and locked and unlocked it and the screen came back on. IDK what fixed it (maybe Triangle Away????) but it's working now! I'm hoping it sticks! I hope no one else has this issue, but maybe this will help!

Sorry for bumping this old thread, but I have found a solution! (at least for me)
There is suprisingly little to find about this issue, so that's why I've made this quick post.
I had this issue as well, but after flashing the stock modem (NON-HLOS.bin) it was resolved. (fastboot flash modem NON-HLOS.bin)
Currently I'm on CM11S XNPH05Q with stock kernel, OnePlus One.
I think it had to do with me going back from CM12 (Lollipop-based) to CM11S (KitKat-based).

help urgently needed

I'm sorry man, but I have no experience with the Galaxy Note 10.1 2014...
I tried to search for a solution, but I couldn't find much since there are all these different versions of the Note 10.1.
I think you have to use Odin to flash custom zips and such for your device.
I couldn't find the modem for the P601 (NON-HLOS.bin), but you could open a new thread asking for it?
I really hope you'll find a solution.
Also, have you tried a factory reset?
If you haven't done anything like rooting, flashing costom ROMs etc, your warranty shouldn't be void and you could return your device.
That's what I'd do.
Best of luck.

Hello mates!
I just had this problem some days ago, when i accidentaly dropped my sm p601. It was working fine so i wasnt worried at that time.
Next day it presented the exact symptoms that you guys described. The screen couldn't be turned on after being turned off, brightness controls not working.
I realized it could be a hardware problem because of the drop that the device suffered, then i stumbled in this topic where our friend scoot05redss mentioned:

Well, since i live in Brazil and we have little to none authorized customer service support from Samsung, i decided to open the device.
(I searched for a disassembly video in youtube. There are one or two avaliable)
It happens that the mentioned LCD ribbon cable is the first thing to pop up when you open the device, so i decided to give it a try, and guess what, it worked.
I just opened the device, lifted the cable lock (that black plastic thing that sits upon the cable) and i gently moved the cable inside the conector (I didn't even had to remove it).
Closed, turned on, everything working as before.
Ps.: Its kinda hard to open the device without the appropriate tool shown in the video, but i managed to open it with a knife, taking maximum care not to leave marks in the screen (the silver frame however couldnt be spared from some scratches.
Thanks for the help!

I can confirm that disconnecting the LCD ribbon cable while the unit is on, reconnecting it, and then rebooting the device fixed the issue for me. My wife accidentally knocked it off her nightstand and while using it during the middle of the next day the screen suddenly faded to black. After noticing that the screen was still on but the back light wasn't working, I popped it open and tried disconnecting the battery but didn't try the LCD ribbon, didn't think that'd make a difference. But I'm glad that's all it was!

Ive got this issue on a grand prime sm-g361h as soon as i lock the screen or it times out thats it, doesn't turn back on until i hard reboot it. super frustrating.. going to try flash a modem to see if it fixes

Color issue after screen off
My Note 10.1 2014 (P605) is ruining smoothly for 3.5+ years without much trouble. Now, it's screen is giving some color issue. Tab boots fine and colours shown correctly. Once screen is off, it start to invert (not sure whether the correct word) colours. Later I observed screen not switching on but accepting touch commands.
I tried color invert setting, it seems not effective. Flex cable was not loose but sometimes reconnecting resolved temporally. Re-flashed the OS but issue came up after few days. This may seems like screen fault, but screen working fine at boot till screen off.
Does anyone have similar experience or advice to help me out.

I was been displayed dark screen (Death screen) by shock on road. Because I put my tablet Samsung note 10.1 P601 (2014 edition) in basket of motorbike. These are solutions:
- Case 1:
If dark screen and the buttons are light up like this question then you need unplug only LCD cable inside tablet and plug again.
- Case 2:
If Death screen and it's no light then you need plug and replug power cable and LCD cable inside table.
" 2 these case you can search and see YouTube How to open and fix black screen Samsung note 10.1 2014"

Living after few months with this problem I can conclude following.
1. It is very difficult to find a pattern for screen to go pink or black. However, I noticed that problem comes frequently when it was used by my baby.
2. Disconnecting and reconnecting LCD cable temporarily resolve problem every time. May be hoangctm is more accurate on procedure.
3. I use this tablet every day. 45min video, 2 x 15min streaming and 1 h reading. Steady use of tablet does not give problems.
4. It is possible to replace LCD flex cable without dismantling screen and this is my next step.

I was also experiencing this issue. What would happen is that my Samsung Galaxy Note 14.1 would work well after a reset but as soon as it locked you couldn't see the screen.
I tried the solution posted in this forum. I opened up the tablet and repositioned the LCD ribbon cable while the screen was active. The tablet is now working well. I can activate the tablet properly after the screen has locked. Thank you all.

Not black SOD but something quite similar

So guys I just got this G3

No flicker no fade to black none of that When the device is on and up and running all is great.....
So here the issue
If I reboot to recovery it boots to black screen with no backlight touch works lcd is working when I shine a light on it....No damage
If I try man Recovery boot seems like when I hold vol down it boots black screen....
So I pop battery again And See what the heck....
Normal boot most of the time works fine lcd works...
It seems like every time I attempt to boot to recovery with the widget Half the time I have to pop bat reboot and try a second time... then it works
Recovery works from widget say 65% of the time
I still have yet been able to boot recovery manually when I do get it to "Turn on" No black screen the button combo does not work...
Other times when it does reboot black screen the system boots fine again touch works everything works but no backlight....
Again also when boot with screen backlight working which is most every normal power boot Never a single issue no lag hanging on off screen nothing....
I dont know If I described this good enough but If anyone does respond I can give more details...
BTW I have tried several times Using flashtool restore stock and start over
Update fresh stock KK works 85% of the time But still does it every now and then.
Still have yet to get the rite button combo for recovery or fac reset mode stock,,,I hav tied many lg button combos, Vol up down left right Press and release I am no newcomer to LGs "fancy"Recovery entry combitnations
but boots screen on to OS every time. And no issues with any 3 of the buttons either
So no matter what its like the Back light is taking several seconds to power on If I shine my light when It happens I can see the device boot normally no backlight in screen
I just so happen to have a spare Screen on hand So I will swap and test it....
Its just weird that when it does power on it works fine

I thought I was the only person on here who answered their own post's. Glad you got it figured out! I've had similar issues but it seems to be related to one particular battery I use as a backup. Not quite the same issue but similar.

I dont know if it was doing it whwn i got it last week. But I rite out of the box. Downgraded rooted and flashed many roms all did the same thing with the screen. Swapped panels every thing. Said screw it I had a g2 that had bad firmware out of the box and the camera didnt work. This one nfc and screen. Tried a diffrent source for kk firmware and its been once again to me as i have already owned a g3. Upgraded to 4 and 5. And am back. The greatest device ever. Even a battery from 2014 getting 3 3.5 hours sot is good for me

Screen Troubles.

Hello everyone, my #og screen was flickering for a while before giving up last December, so I got a new replacement in January. Unfortunately, the new screen didn't last long at all, I was only able to use it for a week before it went dead also.
However, I observed something odd occurring at the bottom of the screen just by the LG logo, this part gets really hot whenever I power on the phone (with the screen dead) . It's odd cause it also occurred right after my #og screen went dead completely.
Please help if you have any idea of what's going on, cause now I'm skeptical of buying a new screen again. Thanks.

(pls pardon the low light shot.)
Does anyone think it might be a panel problem?
The hotness never occurred while the screen worked, even when it flickered. It only started after the screen went dead completely on both occasions like the pic attached.

The crystal has a crack.
You need a new LCD
EDIT:
See for yourself. When there is a damage the screen always is like that.

Even a small crack at the size of a needle can do that same damage.

Thanks for replying. Well, the new screen I got for January never fell from my hand, and there's no crack whatsoever on the glass. Maybe you are right on that, probably over tightening the screw might have reached the inside or something, but should that explain the bizzare hotness that occurs. It really gets hot only at that part, that really bugs me.

When I say there is a crack on the crystal, then there is a crack on the crystal xD
You need a very strong light and a magnifying lens to see it. I told you , even a crack of the size of a needle (head) , a small dot ,tiny one, can do all that you see there.

Have i bricked my phone?

So I got a new screen, it works cause I'm able to boot into recovery. However, I've tried restoring my backup as well as clean installation of various roms but non goes through. After the LG logo (on restart), the screen goes blank but the led indicator shows blue.
*I've had to remove the battery several times to switch off when battling with the previous screen. Could this have been a trigger?
P.S sorry to be a bit of a bother, would appreciate your insight. Thanks

Lucky fix, but what's the bug?

@kessaras, I'm no expert but after tinkering with some settings in twrp i was able to figure out the problem to roms not installing. My procedure:
Wipe system, cache, data, delvik cache.
Restore backup or new rom+gapps.
Wipe cache and delvik cache
Tick off all options in "Mount" (i.e data and cache)
Reboot to system.
Now i don't know the technicality behind this, but usually i don't have to tick off options in "Mount" for me to install/restore roms. So I'm guessing something is wrong somewhere.
